) What is nitrification? How is it different from denitrification?
Answers
Answer:
Hi,
Explanation:
Nitrification is the biological oxidation of ammonia to nitrite followed by the oxidation of the nitrite to nitrate occurring through separate organisms or direct ammonia oxidation to nitrate in comammox bacteria. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification.
Nitrification involves the conversion of reduced nitrogen compounds into oxidized forms. Denitrification involves the conversion of oxidized nitrogen compounds into reduced forms. The end product of nitrification is nitrate (NO3–). The end product of denitrification is either nitrous oxide (NO2) or nitrogen gas (N2).
Answer:
In Nitrification, nitrifying bacteria oxidise ammonia to nitrite and then it is further oxidised to nitrate. Nitrate is thus made available for plants to absorb. Denitrification is the opposite of nitrification. In denitrification, microorganisms reduce nitrate back to nitrogen.
